Examining vanadium (V) geochemistry in organic-rich rocks might provide new insights into
the redox evolution of paleo ocean and atmosphere through Earth's history. Previous work …

Abstract Central Carpathian Paleogene Basin (CCPB, Central Western Carpathians)
comprises mainly Oligocene clastic autochthonous age-equivalents of the widely known …

The thallium isotopic composition (ε 205 Tl) of seawater has been identified as a promising
proxy for global oceanic redox conditions due to its close association with Mn oxide burial …

Thallium (Tl) isotopes are an emerging tool for tracking the history of molecular oxygen in
seawater. Use of Tl isotopes in this manner requires a thorough understanding of the …

Anthropogenic activities have fundamentally changed the chemistry of the Baltic Sea.
According to results reported in this study, not even the thallium (Tl) isotope cycle is immune …

Reconstructing the oxygenation history of Earth's oceans during the Ediacaran period (635
to 539 million years ago) has been challenging, and this has led to a polarizing debate …

Variations of V isotope ratios (δ 51 V) in sedimentary rocks have been proposed as a
potential proxy for paleo-oceanic redox conditions, although the marine δ 51 V system is not …

Abstract Oceanic Anoxic Event-2 (OAE-2,∼ 94 Ma ago) is marked by a significant
perturbation to the carbon and nutrient cycles. Despite the general idea of widespread …

Eight sediment cores from the coastal marine area of the western Saronikos Gulf have been
analysed for grain size and geochemistry. The concentrations of eight metals (Al, Fe, Mn …

Precambrian oceans were overwhelmingly anoxic and rich in dissolved ferrous iron (Fe 2+),
conditions referred to as 'ferruginous'. Yet, few paleoceanographic tools widely applied to …
